I have lived in Wuxi for 5 years, so I will talk about the situation in Wuxi for your reference.
Generally speaking, if you want to find a high-paying technical job, your situation is not very optimistic; but if you want to find a technical job with an average salary, I think it is not difficult to find it. Technology companies in Wuxi are mainly located in Wuxi New District, as well as several research institutes in the city. Most of the companies in the new district are foreign-funded or Sino-foreign joint ventures, with relatively high salaries and busy work; the research institutes are state-owned enterprises, with lower salaries and more leisure. As for private enterprises, I don’t know much about them.
When changing jobs, you need to consider everything comprehensively: If there is a good offer waiting for you now, then resign immediately; if there is no good offer or even no offer, then Do your current job well first, and then look for other opportunities.
You said you really want to engage in technical research, why don't you consider taking the postgraduate entrance examination in science and engineering? I think that as long as you really have the passion to study science and engineering, it shouldn't be difficult to get admitted to a graduate degree, and a graduate degree will make it easy to find a job. Now all Xidian graduate students can do internships at Shanghai AMD. If you are admitted to a graduate school in Shanghai or Nanjing, you can easily work in internationally renowned companies, such as AMD, Nvdia, Cisco, TI, NI, Marvell, etc. There are many technology companies and there is a lot of room for choice.
If you work as an office clerk, you must have a lot of free time and don't have to work overtime. Make use of this time and plan carefully. I think there are still many ways out.
Switching from liberal arts to science and engineering is equivalent to changing industries, so be very careful. I was originally engaged in science and engineering, but I just changed jobs (from integrated circuits to PD) and found it quite difficult. It took me half a year to adapt.
If you not only have the enthusiasm for science and engineering, but also have considerable ability, then change it immediately. I believe you have a bright future! You have just graduated, and you are very discerning in thinking about your future at such a young age. Unlike me, I was in a daze after graduation and wasted more than 7 years before thinking about my future. Good luck!
